DescriptionCVE.org

The Creative Mail - Easier WordPress & WooCommerce Email Marketing plugin for WordPress is vulnerable to SQL Injection via the 'checkout_uuid' parameter in all versions up to, and including, 1.6.9. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the has_checkout_consent() method. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

AnalysisAI

Unauthenticated SQL injection in the Creative Mail - Easier WordPress & WooCommerce Email Marketing plugin (versions up to and including 1.6.9) allows remote attackers to append arbitrary SQL clauses through the 'checkout_uuid' parameter handled by the has_checkout_consent() method. The flaw stems from missing escaping and the absence of a prepared statement, enabling extraction of sensitive database contents from any WordPress site running the vulnerable plugin. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

Technical ContextAI

The Creative Mail plugin, distributed by Constant Contact, integrates WordPress and WooCommerce stores with the Creative Mail email marketing service. The vulnerability is a classic CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) in the DatabaseManager.php file at line 298, where the 'checkout_uuid' value supplied via the CheckoutManager flow is interpolated into a SQL query without being passed through wpdb::prepare() or properly escaped. Because WordPress plugins execute queries with the database privileges of the WordPress user, any successful injection can read across the wp_users, wp_usermeta, and WooCommerce order tables, which typically contain password hashes, session tokens, and customer PII.

RemediationAI

No vendor-released patch identified at time of analysis - the provided references point only to the vulnerable 1.6.9 tag and trunk, not to a tagged fixed release, so administrators should monitor the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/39c17935-a853-407f-a99d-3828561919e6?source=cve and the plugin's WordPress.org page for an update beyond 1.6.9 and upgrade as soon as it ships. Until a fix is available, deactivate and remove the Creative Mail plugin if email marketing automation is non-critical (trade-off: loss of Constant Contact integration and abandoned-cart consent flows), or front the site with a WAF (Wordfence, Cloudflare, Sucuri) configured to block SQL meta-characters in the 'checkout_uuid' parameter (trade-off: legitimate UUIDs are alphanumeric-with-hyphens, so strict allowlisting is feasible but may need tuning for any non-standard checkout flows). Additionally restrict direct database account privileges to the minimum WordPress requires and rotate any secrets that may have been exposed if exploitation is suspected.
